[Ingrid233840771i8j]

I want to install a new version om Dream Weaver but get the message ”No internet” when I click on the programme symbol and try to install.

[BenPleysier]

Which version of Dreamweaver?

What operating system?

Are you connected to the internet?

[Ingrid233840771i8j]

The version is 21.3

macOS High Sierra, intel Core 17

Yes I am connected to internet, I have downloaded the program but can't install it.

regards Ingrid

Do you have a firewall running? Can you try temporarily disabling it for the installation?

I got to know the problem. I have to upgrade the system from macOs v10.13 to minimum v10.14

Make sure your computer meets the minimum CPU & GPU requirements. Most Creative Cloud apps work on:

• Windows 11 (64-bit), Windows 10 versions 21H2, 21H1 (LTSB branches are not supported;)
• mac OS 13 (Ventura), macOS 12 (Monterey), macOS 11 (Big Sur), macOS 10.16 or 10.15 (Catalina).

Mojave and earlier are no longer supported by Creative Cloud Desktop App.  Adobe expects users to have the latest OS, not more than 2 versions back.
